Sorry to hear about your experience. Let me share a similar tale with you. We were swinger virgins last year. We met a couple and we became friends. THey disclosed that they were swingers and became our "mentors." THey were soft swap and strongly encouraged us to be soft as well.
Well, to make a long story short, we became full swap and they became very "weird" toward us. They made comments regarding how we would be seen as loose. Needless to say, we are not friends anymore.
The moral of the story is that every couple must make their own decision regarding their swinging activities. It is not fair for others to judge your activities.
